Subject: [PATCH] BUILD: fix coexistence of openssl and zlib

The crappy zlib and openssl libs both define a free_func as a different typedef.
That's a very clever idea to use such a generic name in general purpose libraries,
really... The zlib one is easier to redefine than openssl's, so let's only fix this
one.
